Hello All, About to do my first .223 reloads...this is what I am planning. These will be shot out of a Stag Model 2 AR. Using data from about 5 sources. Speer, Lee, Sierra, etc. Once fired Remington UMC Cases trimmed to 1.1750 CCI #41 Primers H335 Powder Rem FMJ 55gr OAL- 2.230 (Brings me to just under the top edge of crimp groove) Slight crimp with lee crimp die I am planning on doing 10 rounds each with 23.5gr, 24gr & 24.5 gr. Thoughts?? Thank You!!
